Hi Team,
My processor: RZG2N
Package: VLP3.0.5 (RZ/G Verified Linux Package v3.0.5-update1(RTK0EF0045Z0021AZJ-v3.0.5-update1.zip)
I have a requirement to show the uboot logs and especially a Logo of my client when the system is in uboot. Since it take couple of seconds to reach the user space and the drivers to be active, we need to show a logo on our LVDS display screen as soon as the system turns on.
I have a rough Idea on what to be done. I have explained my idea below.
Please provide an example on how to achieve this. Since I have very low experience I am not sure about the above points.
Please let me know if something is missing.
Thanks in advance,
Kartha.

Renesas does not provide video driver support in u-boot.
Hi Chris,

Ok
But is that possible to do it? Means can we make it possible by adding the driver to uboot our self, or this driver integration is not possible in u boot?
Thanks,
Kartha
Yes, the chip 'could' do it. But, I am saying there is no driver code for it today.
Hi Chris Can you please tell me how to enable splash screen in uboot.
I have the build script, using that I am generating the uboot.
Please let me know what all configuration changes i need to do uboot to enable the splash screen.
I have seen some macros are there for doing this, likeCONFIG_SPLASH_SCREENHow to properly do this and see a logo image during booting.Thanks and regards,Kartha.
Hi Kartha,this hack of the yocto recipes exchanges the "yocto" logo:
cp logo.png ../poky/meta/recipes-core/psplash/files sed -i 's/^SPLASH_IMAGES = "file:\/\/psplash-poky-img.h;outsuffix=default"/SPLASH_IMAGES = "file:\/\/logo.png;outsuffix=default"/g' ../poky/meta/recipes-core/psplash/psplash_git.bb
Hi Stefan,
I am using build script instead of yocto for building uboot.
In Kernel I have integrated a splash screen. Same thing I need to implement in uboot, so I can see the intended logo instead of uboot logs.
Hope you understand the requirement.

There are no Renesas display drivers in u-boot.

I understand what you are saying. But, there are no LCD drivers in Renesas u-boot.
